A small cube capable of taking hold of solar wind is to be Estonia's first-ever satellite
NASA heads for the future with technology from the past with plans to launch the largest solar sail ever unfurled into space next year.
Solar sails harness the pressure of the solar wind to propel spacecraft across the solar system essentially for free, without the need for engines or fuel. An electric solar sail works more or less the same way, except without the sail: all you need are a bunch of wires.
Japan's Ikaros solar sail spacecraft has certainly made itself into one to watch. After a successful launch and an equally successful deployment, the ship is now showing off how it maneuvers. High tech as the ship is, its method of steering is simple and genius.
